HARRIET HILL, OF NEW YORK, N. Y.

SANITARY DRINKING-CUP.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed June 19, 1912. Serial N 0. 704,594.

To all whom it may concern:

Be it known that I, HARRIET HILL, a'citizen of the United States,residing at 127 East Fiftieth street, New York city, in the in a vendingmachine that the possibilityof their jamming or catching one onto theother when the machine is operated, will be reduced -to a minimum. Andto this end the invention consists in providing the cup with a lipflange arranged so as to lock the lon-.

'tudinal plaits of the cup against unfoldlng under the pressure of waterin the cup, and to present a smooth outer surface which will have notendency to catch onto the mechanism of the vending machine and whichwill conform more readily to the space between the lips of the user whenthe cup is in use.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawings forming a. part thereof, 1nwhich:

Figure 1 is a perspective of the device. Fig. 2 is a detail sideelevation of a portion of the upper end of the cup preparatory toforming the flange. Fig. 3 is a detall vertical section showing theflange partly formed. Fi 4 is a view similar to Fig; 3 showin t e nextstep in forming the flange. *ig. 5 is a view, similar to Fig. 4 showingthe position of the flange when the cup is ready for use.

The cup a is formed of waxed, or waterroofed paper or such othermaterial as is used in the manufacture of devices of this kind and is bypreference frust'o-conica'l in contour. The usual strengthening ribs inthe form of longitudinal plaits are employed for preventing thecollapsing of the cup under ordinary pressure on the exterior thereof.

In carryin out my invention and after the cup is s aped and plaited, theupper edge portion is folded downwardly and outwardly as indicated at 6,and as clearly shown in Fig. 3. The said upper edge portion is thenrefolded outwardly. and downwardly from a point a trifle below the edgeof the first folded portion 6 and as indicated at 7 in Fig. 3. Uponth-erefolding of the upper edge portion the folded portion 6 will extendupwardly so that the lower edge of the now-f0rmed flange 8 will be bluntas contrasted with the free edge of the folded portion 6, which wasprior to its being folded, the raw edge of the paper itself.

With the flange thus far formed as shown in Fig. 4, the cup may be usedin the ordi nary manner, but the presence of the lower edge of theflange forms a projection which will readily catch onto any unevenportion in the holder of the vending machine and thereby prevent thesuccessful operation of such machine and at the same time the tagoredspace between the inner face of the ange and adjacent surface of the cupforms a convenient socket for the edge of the cup immediately thereunderwhile the cups are in a vending machine, so that if the cups be tightlynested one into the other in such machine, there will be great liabilityof the upper edge of one cup to bind in the socket of the cup which itreceives. Therefore, in order to overcome such defect, the flange whenpositioned as shown in Fig. 4, is subjected to the pressure of asuitable machine which will effect the compression of the said flangeonto the outer face of the body of the cup and at the same time flarethe flange outwardly. Under the aforesaid pressure, the inner face ofthe flange will be pressed into cont-act with the adjacent surface ofthe cup, and inasmuch as the folded portions which constitute the flangemust contract in order to conform to thejdiameter of the portion of thecups into which they are forced in contact, it will be obvious that uponsuch contraction the plaits of the flange will telescope one int-0 theother so sequently prevent such plaits from unfolding under the pressureproduced by the contents of the cup.

What is claimed as new is:

1. A sanitary drinking cup comprising a cup-shaped body of waterroofmaterial havin ongitudinal plaits, t e laitedupper edge portion of saidbody dieing bent upon itself and folded over and pressed onto one faceof the body and flared with respect to: the portion of the bodytherebeneath. a

2. A sanitary drinking cup. comprising an upwardly flared cup-shapedbody of waterproof material havingv longitudinal plaits, the plaitedupper 'edge portion of said body being bent upon itself and foldedoutwardly and ressed onto the outer face of the body and ared' withrespect to the portion of the body therebeneath.

In testimony whereof I aflix my signature in presence of two witnesses.
